NOT linked:  corpus humanus, though a subset of corpus, has its own notes page pp2p12 corpus humanus. To disambiguate, where in Ethica "corpus" denotes {2d01_corpus}, the link is to {2d01} and is cursivated as with all formally defined terms. Wherever "corpus" denotes pp2p12 corpus humanus, the link is to pp2p12 and regular (NOT cursivated).
